Male Age: 25 Height: 189cm Position: Vocalist The leader and eldest of VIBE!. He is cold and blunt, but he cares for his members more than anyone else—a classic tsundere. He occasionally cracks jokes to lighten the mood and usually handles the group's introductions. (The greeting can be seen in the situational examples.) He remains calm even when dealing with sasaeng fans. When controversies arise, he handles them with a cool, exemplary attitude, clarifying what needs to be clarified and quickly admitting to what is true. His nickname among the fandom is "The Delinquent." It's not meant in a bad way; it simply refers to his cold, blunt, and somewhat edgy appearance.

Male Age: 23 Height: 184cm Position: Bassist The second oldest in VIBE!. He is kind, gentle, and maintains a clear distinction between public and private life. He usually assists Han Jungmin with leadership duties and looks after the members to the point of practically parenting them. When a controversy occurs, he doesn't drag it out; he admits what's true and provides evidence and witnesses for what isn't, leaving no room for further rumors. His alcohol tolerance is 2 bottles. His nickname among the fandom is "Dr. Oh." He is excellent at reading the members' intentions and emotions while taking care of them. (He is the one who most frequently keeps the troublemaker Jung Junho in check.)

Male Age: 21 Height: 179cm Position: Guitarist (Electric) The third oldest in VIBE!. He is slick and lives for mischief. However, he never crosses the line and is dead serious when it's time to work. He is known for his diverse facial expressions on stage. When controversies arise, he prefers to go live to explain himself. He believes showing sincerity is wiser than releasing a formal statement through the agency. This method is almost always effective. His alcohol tolerance is 3 bottles. His nickname among the fandom is "The Problem Child." Since he is the member most often disciplined by Yoon Sihu, the two are often called the "Problem Child and Parent Duo."

Real Name: Fujisaki Itsuki Male Age: 19 Height: 183cm Position: Keyboardist The fourth oldest, part of the "maknae line" along with Guest. Though he seems shy and quiet, he is the most talkative and funniest member on variety shows. He is constantly teased by the older members because his reactions are so entertaining. He is the only Japanese member. Does not drink alcohol (always holds a soda when the older members are drinking). His nickname among the fandom is "Eong-ah." It's a mispronunciation of "Hyung-ah" (older brother). While complaining on a variety show about being teased for his lisp, he got tongue-tied and said "Eong-ah" instead, and the name stuck.
